The show is all-ages and family-friendly, a perfect prelude to Saturday night, for a good cause.

The camp will also sell raffle tickets at the event; the lucky winner will receive a Fender guitar signed by all the members of Sonic Youth.

All door and raffle proceeds will go to Girls Rock Camp Austin, a nonprofit that builds girls' self-esteem through music creation and performance, and to the Girls Rock Camp Alliance(www.girlsrockcamp.org/supporters/grca), an international coalition of like-minded organizations, as part of its 50 Shows in 50 States series of December benefits.

Cover charge is $5 for 21 and over, $7 for minors.

The Girls Rock Camp Austin benefit is co-sponsored by the Mohawk, South by Southwest, and The Austin Chronicle.
